So I have had an old discontinued Ikea Lival Lamp lying dormant for years as the plastic swivel arm between the lamp and the main articulated arms snapped.
So i finally got round to modelling and printing a replacement.
I have included the Fusion 360 file and a STEP file if anyone wants to mod. I was thinking about a 14/-20 adaptor for things like the [Universal Phone Tripod Mount](https://www.thingiverse.com/thing:2423960) by [jakejake](https://www.thingiverse.com/jakejake/designs)
There is also a replacement articulated arm to clamp base I have modelled as mine also snapped as it was just thin stamped metal.
